Gadget34 Posted March 8, 2021 Share Posted March 8, 2021 Looking at updating my scantronic alarm to a smarter model and this seems to be a common diy choice. I have done some reading and have the below questions. 1) To enable communication for the app control and alerts I will need a communication module. If I wanted a backup for WiFi (broadband) failing could I just install the gprs module and use a SIM card for app alerts and sms alerts or would I need both modules? 2) Do the modules fit in both panel cases the small/large or do I need the large one? Thanks Quote Link to comment Share on other sites More sharing options...
MrHappy Posted March 8, 2021 Share Posted March 8, 2021 Unless I'm mistaken.... You can either have a lan card A wireless card or card which sends Texts & only 1 fitted to the system ? (inside the metal case) Quote Mr Veritas God Link to comment Share on other sites More sharing options...

Gadget34 Posted March 8, 2021 Author Share Posted March 8, 2021 So only one connectivity card can be installed? I guess I best stick with the WiFi one unless the gprs one can do everything? Obviously will need a SIM card but more robust. Quote Link to comment Share on other sites More sharing options...
